Answer:
$14,362
Step-by-step explanation:
The computation of the minimum unit cost is shown below:
Given that
0.6x^2 - 108x + 19,222
And as we know that the quadratic equation form is
ax^2 + bx + c
where
a = 0.6
b = -108
c = 19,222
Now for determining the minimal cost we applied the following formula which is
![= \frac{-b}{2a} \\\\ = \frac{-(-108)}{2\times 0.6} \\\\ = \frac{108}{1.2}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-b%7D%7B2a%7D%20%5C%5C%5C%5C%20%3D%20%20%5Cfrac%7B-%28-108%29%7D%7B2%5Ctimes%200.6%7D%20%5C%5C%5C%5C%20%3D%20%20%5Cfrac%7B108%7D%7B1.2%7D)
= 90
Now put these values to the above equation
![= 0.6\times 90^{2} - 108 \times 90 + 19,222](https://tex.z-dn.net/?f=%3D%200.6%5Ctimes%2090%5E%7B2%7D%20-%20108%20%5Ctimes%2090%20%2B%2019%2C222)
= 14,362
Some rational numbers are
2.71, 2.72, 2.73, 2.74, 2.75, 2.76, 2.77, 2.78, 2.79
2.711, 2.712 2.713....
2.721, 2.722, 2.723....
2.731....
I think you get the point! Hope this helped!
The correct is answer either c or b.
Answer:
![log_{3} 9 = 2](https://tex.z-dn.net/?f=log_%7B3%7D%209%20%3D%202)
Step-by-step explanation:
for an equation
,
the corresponding log equation is ![log_{a} c = b](https://tex.z-dn.net/?f=log_%7Ba%7D%20c%20%3D%20b)
so your corresponding equation is ![log_{3} 9 = 2](https://tex.z-dn.net/?f=log_%7B3%7D%209%20%3D%202)
